Solar Panels for New Builds
Since June 2022, updated Part L Building Regulations require all new homes in England to produce approximately 31% less carbon than previous standards. In practice, this means most new builds now need solar panels to meet compliance. Manchester Renewables works with developers, housebuilders, and self-builders across Greater Manchester to design and install solar PV systems that meet Part L requirements while maximising homeowner value.
We provide a complete service from SAP calculation support through to MCS-certified installation and handover. Whether you are building a single self-build property or a development of 200+ homes, our team fits in smoothly with your construction programme to install solar at the right stage — avoiding costly delays and rework.
What Is Included?
SAP Calculation Support
We work with your SAP assessor to model solar PV contributions, so your design meets Part L carbon reduction targets before construction begins.
System Design for Each Plot
Every plot receives a bespoke design considering roof orientation, pitch, available area, and predicted occupant energy demand.
In-Roof & On-Roof Options
We offer integrated in-roof systems for a sleek aesthetic on premium developments, or standard on-roof mounting for cost-effective compliance.
Phased Installation Programme
Our team works to your build schedule, installing at the right stage of construction to avoid weather damage and coordination issues with other trades.
MCS Certification Per Plot
Each property receives individual MCS certification, allowing homeowners to access the Smart Export Guarantee from day one of occupation.
Part L Building Regulations 2021: 31% Carbon Reduction
The 2021 update to Part L of the Building Regulations (effective June 2022) requires new dwellings to achieve a 31% reduction in carbon emissions compared to 2013 standards. Solar PV is the most common and cost-effective way for developers to meet this target, with the Future Homes Standard (expected 2025) set to increase the requirement to 75-80%.
Why It Matters
- Part L compliance is mandatory — solar PV is the most cost-effective route for most new build designs
- Homes with solar panels sell faster and attract higher prices, adding value to your development
- MCS certification for each plot enables homeowners to claim SEG payments immediately
- In-roof solar integrated at build stage costs less than retrofitting and delivers a cleaner aesthetic
Cost Guidance
New build solar installations typically cost £1,200-£2,000 per kW when installed at scale during construction — significantly less than retrofitting. A typical 3-4kW system per plot costs £3,500-£6,000 depending on panel type, mounting method, and access. Volume discounts apply for developments of 10+ plots. We provide fixed-price quotations per plot for budget certainty.
